Package Parasitics

Hello,

I am new to the IBIS game so pardon my simplistic question. I would like
to know the meaning of the values in an IBIS model:

[Package]

|variable typ min max

R_pkg 250m 200m 300m

L_pkg 8nH 5nH 12nH

C_pkg 0.7pF 0.56pF 1.2pF
|

I have found other models that have these values set to zero:

 
> > > [Package]
> > > R_pkg 0 0 0
> > > L_pkg 0 0 0
> > > C_pkg 0 0 0

Can you explain why these values are used, i.e. why the model would be
realistic with no package parasitics?

Thanks for your help.

Best regards,
